Also known as Deception IV: Blood Ties for the English release. There hasn’t been a new entry in the series in almost 10 years, if I’m not mistaken. The main complaint I’m seeing now is that the characters don’t fit in with a dark game like Kagero. Is that really the case, or is it just the older crowd from the PS1 era showing their usual aversion to the anime aesthetic?

Kaihou Shoujo aka Liberation Maiden was originally a shooter for the Nintendo 3DS. As part of the Guild Series, it involved a collaboration between developer Level-5 (Dark Cloud 2, Dragon Quest VIII, Ni no Kuni) and game director Suda 51 (No More Heroes, Killer is Dead, Lily Bergamo) with animated cutscenes from studio Bones. SIN is the sequel to that story told in visual novel format.
